Figure 2
The photo shows an elevated view of a production area in a factory featuring multiple parallel rows of metallic racks and yellow safety rails. Fencing and access gates border the workspace, and a section of the back wall has the label “Loading bay door.” Bright red arrows are overlaid atop several rack rows, visually guiding the route that parts or finished subassemblies take as they move from the foreground production area toward the back of the workspace, where the loading bay door is located. The arrows trace a path first across, then parallel, and finally back across the racks, indicating a looped or zigzag flow. On the right side of the photo, descriptive text explains the process: “The red arrows show how the finished subassemblies are moved from the production line to the loading bay door where empty racks returning from the O E M are first unloaded, before the racks with subassemblies are loaded onto the trailer. The completed subassemblies are attached to the racks in the production.”Image showing the L/UL solution in Case 2
